Networking Win 98 to Win Server 2003

My company has 8 computers networked to a windows 2003 server. All of these have Win XP Proffesional installed on them. I am trying to add a computer that has win 98 on it. I need to know if this is possible and if so, what do I need to do to get the computer with 98 to communicate with the server. The network hookup has already been made. I need to know what configuration changes have to be made.

Thank You
